METHODOLOGY HIRARC process flow chart shows the step taken in order to finish this report. The very first step was classifying work activities it was conducted by observing and identifying all of the activities done in the room. After the activities were identified, it was break down into a few sub-activities. Second step taken was identified hazard and its consequences. Third procedure was analyzed and calculated the risk assessment. Basically, risk is the determination of likelihood and severity of the credible accident or event sequences in order to determine the magnitude and the priorities identified hazard. Likelihood is an event likely to occur within the specific period or in specified circumstances. Below is the Likelihood rating used in this report: Likelihood
Example
Rating
Most Likely
The most likely result of the hazard being relised
5
Possible
Has a good chance of occuring and is not unusual
4
Conceivable
Might be occur at sometimes in future
3
Remote
Has not been known to occur after many years
2
Inconceivable
Is practically impossible and has never occured

Severity is outcomes from an event, such as severity of injury or health to human, severity of damage to property, or severity of contamination to environment or any combination of the event.
Below is the Severity rating used in this report: Severity
Example
Catastrophic
Numerous
Rating fatalities,
irrecoverable
property
damage
and 5
productivity. Fatal
Approximately one single fatality, major property damage if 4 hazard is realised
Serious
Non-fatal injury, permanent disability
3
Minor
Disabling but not permanent injury
2
Negligible
Minor abrasions, bruises, cut, first aid treatment type of injury

Director General of Department of Occupational Safety and Health, Guidelines for Hazard identification, Risk Assessment and Risk Control (HIRARC), 2008 Based on both likelihood and severity rating, a hazard risk or risk level can be calculated by using "Risk Level = Likelihood x Severity".

Director General of Department of Occupational Safety and Health, Guidelines for Hazard identification, Risk Assessment and Risk Control (HIRARC), 2008 Hazard risk was divided into three categories which were high, medium and low. It was classified by using the risk matrix and risk level calculated. Hazard labeled as high risk need an immediate action to reduce or eliminate the hazard.
Table below show the categories of risk and the action required:
Risk
Description
15 - 25
High
Action A HIGH risk requires immediate action to control the hazard as detailed in the hierarchy of control. Actions taken must be documented on the risk assessment form including date for completion.
5 -12
Medium
A MEDIUM risk requires a planned approach to controlling the hazard and applies temporary measure if required. Actions taken must be documented on the risk assessment form including date for completion.
1-4
Low
A risk identified as LOW may be considered as acceptable and further reduction may not be necessary. However, if the risk can be resolved quickly and efficiently, control measures should be implemented and recorded.
Director General of Department of Occupational Safety and Health, Guidelines for Hazard identification, Risk Assessment and Risk Control (HIRARC), 2008 The last procedure was prepared risk control action plan. Based on hierarchy of control, there are six different methods that may be use for an improvement. Hierarchy of control start with elimination where getting rid of a hazardous job, tool, process, machine or substance is perhaps the best way of protecting workers. Secondly was substitution of hazardous equipment with less hazardous equipment. Next, engineering control through modification of equipment or work environment. After that, isolation or separate the hazard from the person, or the person from the hazard. Next was administration control which was to reduce the exposure of hazard to workers through proper instruction. Lastly was personal protective equipment which other controls measures are not feasible but additional protection is needed.
